Problems solved by technology

[0003] CN109487360A provides a kind of polyester fiber containing plant extract, it adds many kinds of compound plant extracts and many auxiliary components such as hexacyclic stone powder, halloysite powder and surface active phospholipid when preparing polyester fiber, although also can effectively improve polyester fiber Antibacterial performance, however, its preparation process is relatively complicated, plant extracts and auxiliary materials need to be prepared separately and react in multiple stages, the reaction rate is not high, and the final prepared polyester fiber containing plant extracts, plant extracts are easy to lose components
[0004] CN201910546151.X discloses a preparation method of polyester fabric. The polyester yarn is bleached, soaked, etc., so that citronella oil, chrysanthemum, mint leaves and cocklebur are added to the polyester fabric as mosquito repellent ingredients, which can make the polyester fabric have repellent properties. Mosquito effect and prolong the use time of mosquito repellent, but it impregnates the fabric with plant extracts by soaking. The organic components still volatilize quickly when exposed to high temperature conditions such as hot water and ironing, and the preparation process is complicated. Equipment High occupancy rate and high production cost

Abstract

The invention provides mint polyester master batch and a preparation method thereof. The mint polyester master batch comprises 0.1-5% of mint extract and 1-6% of nano negative ion powder. Specifically, the preparation method of the master batch comprises the following steps: preparing the mint extract, preparing the modified SiO2 powder containing the mint extract, premixing the components, carrying out melting granulation, and drying the grnaules with hot air. The mint terylene master batch prepared by the process contains negative ion components, can adsorb peculiar smell and release bactericidal negative ions, and has a bacteriostasis rate of 97.0-99.5% for staphylococcus aureus, escherichia coli, candida albicans and other bacteria which are easily infected by a human body; the mint polyester master batch has a melt index of 2.2-2.6 g / 10min and a melting point of 128-130 DEG C, so that the solid particles are convenient to store and use, and the mint polyester master batch can be sold independently as an intermediate product.

Description

technical field [0001] The invention belongs to the field of composite material preparation, and in particular relates to a mint polyester masterbatch and a preparation method thereof. Background technique [0002] With the continuous improvement of science and technology, people's living standards are also constantly improving, and people's requirements for the fabrics they wear are also increasing. As a common fabric in fabrics, polyester has the biggest advantage of wrinkle resistance and durability. The shape is very good, so it is suitable for outerwear, and at the present stage, for outerwear fabrics, its antibacterial health care performance is the most demanded by people. [0003] CN109487360A provides a kind of polyester fiber containing plant extracts, it adds many kinds of compound plant extracts and hexacyclic stone powder, halloysite powder and surface active phospholipids and many auxiliary components when preparing polyester fibers, although it can also effect...
